Strengths: Excellent crankset with a good value and removable spider to go 1x10.

Weaknesses: Chainline a bit too much to the right to my taste.

Bottom Line:

While it's not the hottest carbon crank like the X0/XX, the construction quality is surprisingly very good and light enough while being build for AM. Mine is the 2.1 AM with a 24/36 chainrings and bash guard. It also include a GXP BB in the package so it's a great deal. Installation is very easy but it require the right tools like the Park Tool BBT-19 to install the GXP BB. The crank is very smooth and pretty stiff despite my weighty (a hair under 200 lbs) and the chainrings is made from some quality steel.

The biggest advantage of this crankset is that it feature a removable spider like the X9/X0/XX so you can go to a 1x10 setup with a direct mount chainring like a Wolftool Component or Absolute Black. You can shave a lot of weight doing that without needing to buy a more expensive crankset.

Strengths: Use mine with a MRP bling ring. Great set-up. I've had no problems. No issues with the GXP bb. I'm 250lbs, and I notice no flexy-stuff. Finish seems pretty tough too, but I've only been on them for 6 months. For the price, they're hard to beat.

Weaknesses: None so far. Tempted to buy another set when I find them under $100 because it looks like a model that might not stick around.

Bottom Line:

What's to review? Get yourself a set, especially if you're going to change the rings anyways and go single ring. I was told in the Sram forum that these cranks are no different that the X9 set, but for some differences in the chainrings. If you can find a set of these cranks for under $120, it's a big time win for you.

Strengths: Light crankset, decent price, sleek and simple appearance, puts up with a lot of abuse.

Weaknesses: None yet.

Bottom Line:

I bought the 2x AM version of this crankset (24/36/Bash), and I love it. The bash is solid aluminum and has stood up to a couple rock and log hits with no bends or breaks. I've also smashed the non-drive side crank arm deep enough to scratch into the aluminum, but it didn't fail. This is a very similar crankset to the Shimano SLX, but you get a solid aluminum bash, and it's $25-50 cheaper.

This comes with a newly designed GXP bottom bracket as well which seals off the bearings better than the original. No complaints after riding this 2x9 setup for the last 4 months.

Got this as a replacement to my Fire x there was on its way out. I was surprised by they crankset. Similar to the Sram S140. The chain ring combo is great (36-24) plus you get the bashguard. Crank arms are pretty stiff. Pretty satisfied so far.

Just watch the non drive side washer on the gxp bb during the installation.
